Abstract
(EN) The present invention patent relates to a method for producing an activated/calcined clay composition using a calcium aluminoferrite or calcium ferrite fraction and to the clay composition produced by said method, pertaining more precisely to the field of industrial cement manufacturing, said method including a process for forming calcium aluminoferrite or calcium ferrite in situ for producing an activated/calcined clay from red clay that is of better value for being added to cement compositions.
(FR) La présente invention concerne un procédé d'obtention d'une composition d'argile activée/calcinée avec une fraction d'aluminoferrite calcique ou de ferrite calcique et une composition d'argile obtenue au moyen dudit procédé, et relève plus précisément du domaine de la fabrication industrielle de ciments, ledit procédé comprenant un processus de formation d'aluminoferrite calcique ou de ferrite calcique in situ pour obtenir une argile activée / calcinée à partir d'argile rouge, préférée en vue d'une addition à une composition de ciment.
(PT) A presente patente de invenção trata de método de obtenção de composição de argila ativada/calcinada com uma fração de aluminoferrita cálcica ou ferrita cálcica e composição de argila obtida pelo citado método, mais precisamente pertencente ao campo da fabricação industrial de cimentos, onde dito método revela processo de formação de aluminoferrita cálcica ou ferrita cálcica in‐situ para entregar uma argila ativada / calcinada a partir de argila vermelha que seja mais apreciada para adição a composição do cimento.
